For the long-range transport of large-scale wind power as well as large regional power grid interconnection issues facing low-frequency oscillations, this paper presents a wide-area damping controller design method applying to the wind farm grid background. Firstly, this method use multi-element multiinnovation recursive least square algorithm improve the ARMA model identification methods, using the...
With regard to the interval low-frequency oscillation problems in large-scale interconnected power system, a design method based on Fruit Optimization Algorithm (FOA) for the wide-area time-delay damping controller is proposed in this paper. Systems such as the New England 10-generator 39-bus system is employed to validate the effectiveness of the method presented. The system is linearized at first,...
As the proportion of installed capacity of wind power in total installed capacity continues to increase in China, the influence of the wind farm when dealing with the stability problems of interconnected power system is considered, and a wide-area time-delay damping controller to suppress inter-region low frequency oscillation is designed. In order to obtain a more accurate transfer function model,...
The practical economic dispatch (ED) problems have many non-convex characteristics, which makes the searching of the global optimum difficult when using traditional mathematical methods. This paper presents a novel hybrid algorithm (HA) to the ED problems based on the particle swarm optimization (PSO) technique and differential evolution (DE) algorithm. Since the standard PSO has the adversity of...
